March 23, 200422 yr ok 87 gl-10 turbo recently on start up when its been sitting for a while all the idiot lights have a soft glow to them rev the engine a bit it goes away let off it comes back after a while it goes away compleatly until it sits for a few hours i am personally thinking its a crappy ground under the dash but i don't know wich grounds to look at first and since it the only car i ahve right now to get to work and back i can't have everything torn apart for a day or 2 to chase it pretty sure its not a ground under the hood since i just redid/added more about 3 weeks or more ago btw will a regular analog gauge cluster plug inplace of a digi gauge?
March 23, 200422 yr Thats usually the diodes in the alternator starting to go south. Replace ALT asap to keep digi dash alive. Have the alt tested at a parts store to be sure. Some places even have on car testing for free.
March 23, 200422 yr Author hmm the alts not that old.. but .. i have been giving jump starts to idiots .... perhaps its time to fabricate a bracket and just put a trusty chevy alternator on it.. or even this saab alternator better than 90 or so bux again
March 23, 200422 yr I agree with Shawn on this. Same thing happened with my alternator. These lights are in the field circuit to the alternator and it is a heads up warning about the alternator. They go out when you rev the engine because the alternators' output goes up also.
March 25, 200422 yr Author interesting i yanked the alt and ac out at work last night had to wrestle with the 2 prong plug on the alt a bit got it out took off the ac so i had less crap in the way put it all back in minus ac and the problem went away... i am thinking corroded connectors on the alt?? still gonna do a gm conversion just not so high priority now
